Performance tuning for the XO

[C. Scott Ananian]

We make currently make heavy use of hashing in our upgrade &
verification infrastructure.  I'd like to find the fastest possible
implementation of the SHA-256 and/or RIPEMD-160 algorithms.  Can
anyone offer me advice on the proper compilation options and
strategies for maximum performance on the processor in the XO?  I
don't see the -mxo option to gcc yet.
